MOP AND SHAKER Ron Filed June 2e, 194s INVENTOR. JOSEPH R BEM A TTon/vn.

Patented July 7, U1953 UNITED STAT oFFl'cE 3 Claims. (Cl. 15-147) Thisinvention relates to improvements in mops and brushes and shaker rodstherefor, and more particularly relates to shaker rods for oscillatingthe head of a mop having exible tufts or strands forming an aggregatemop head which is usually mounted at an end of an elongated handle.

Since the invention would be equally advantageous with a mop head or abristle brush, the general term mop is used inclusive of both of saidfacilities.

Mops of the type having a head of flexible tufts or strands mounted atthe end of a handle are well known for dusting or swabbing surfaces.These types of mops almost invariably have a pivot connection betweenthe mop head and handle so that the handle may be adjusted at varyingangles to the mop -head for ymore convenient .use of the mop atdifferent positions of manipulation, for inserting vthemop head intonarrow spaces, such as under furniture, for change of mop head when wornout, for shaking the accumulations of dust or dirt from the mop strandsand for other purposes.

The present invention has among its objects to provide means foroscillating a mop head on its pivotal connection with a handle member.

A further object is to provide a mop shaker rod device readily andeasily attached to a mop assembly of head and handle.

Other objects are to provide resilience in a rod for shaking a mop headfrom a position on the mop handle; to provide stop means for abruptlydelimiting the oscillations of a mop head when shaken by a shaker rod onthe mop handle; to provide shaking means for a mop head which iseconomical to manufacture, rugged in construeF tion and efficient inoperation, and generally to improve upon devices of the characterdescribed.

With the foregoing and other objects in view, which will be apparentfrom or specifically pointed out in this, specification, one form. inwhich the invention may be exemplified is de scribed herein andillustrated in the several views of the accompanying drawing, it beingunderstood that variations of specic structure may be resorted toywithout departing from the invention which is defined in the appendedclaims.

In the accompanying drawing: i

Fig. 1 is a perspective view of shaker rod of the invention.

Fig. 2 is a fragmentary side view of Fig. 1 partly in section.

Fig. 3 is a fragmentary perspective of a part of the structure of Fig.1, partly broken away.

Fig. 4 is a fragmentary crsssection on lin 4 4 of Fig. 2.

Fig. 5 is a modied form of handgrip member.

Fig. 6 is a perspective view of modified form of frame member.

Fig. '7 is a side view partly in section of a portion of frame member ofFig. 6, showing positions of operation.

Referring to the drawing in which like reference characters indicatecorresponding operational parts in the several views, and particularlyreferring to Figs. 1 and `2, an elongated conventional handle member I0of a suitable length is provided at its connecting end with a ferrulesocket II having an extended arm I2. rlhe extended ferrule arm has anopening or eye I3 adjacent its free end, by which a mop head or brush,generally indicated I4, may be pivotally secured thereto.

The mop head may be made of any suitable type having a back member orother suitable means to which the ferrule armA of the handle may bepivotally connected. As illustrated herein, the back of the mopcomprises an open frame I5 of the nature of a broken loop generallytriangular in plan and having a break in continuity as to be open at oneangle portion as at I5 for 'sliding thereon a padded flexible tubularStringer Il for the mop, the strands or tufts I8 of the mop beingsecured to the Stringer in any suitable manner. The mop member istherefore readily removable and replaceable on the frame, either forlaundering or mounting a new mop member. Opposite the opening IE thetriangular frame may have bracket IS extended inwardly and forwardlyfrom its rear base bar toward its central portion and formed byretroverting the frame member upon itself providing a retroverted loopedend leb, as shown in Fig. 3. rIfhe bracket arms 20 and ZI which areconnected at one end by the looped end |91) of the bracket arerelatively spaced and parallel andvhave an eyelet at 22 therethrough forregistering with the eyelet I3 of the extended arm of the handleferrule, so that a pivot pin 23 may be inserted therethrough, wherebythe frame of the mop head and the handle are connected pivotally.

Within the triangular frame and the padded tubular Stringer I'I which isslid thereon from the open angle, there may optionally be provided K apan or plate 24, which would correspond withy the back of a bristlebrush. This pan or plate 24 may be fixed in place by an integral centralupformed ange on each side of the centralbracket I9 of the frame andsecured thereto by the pivot pin 23. The pan or plate 24, when employedwith an oil or liquid mop, may have holes 26 therein so that oil orother liquid may be placed in the pan, and be absorbed into the mopbody. As is sometimes customary, Wire loops 25 may be passed through theholes 26 and around the Stringer I'I and intertwisted at the ends tofurther support the pan. As described thus far, themoppf Eigs. 1 and2are ,Well known. Y One-featureof this finventgiongisto provide animproved means whereby the mop head may be oscillated upon the pivotalmounting with the handle for shaking from the mop strands, or frombristles in a brush, the accumulation.odustidirt, fibers and othermatter collected o n, the mop or brush by its use. Such a means, asYexemplified in Figs. l and 2 is especially adapliods: an.,a.uxi1 iaryattachment for mops or brushes previously constructed Without suchfacility, whereas in Figs. 6 and 7 as will be further described, a1speciallydesigned'fframefistprovided.

The upformed end 19a of the arms of the bracket of the frame has aneyelet therethrough to receive pivot pin 30, the latter being engaged bythe loop eyelet 29 at one end of the shaker rod 21. The hand grip of therod in Fig. 6 may be of either type heretofore described.

Upon reciprocation of the hand grip member and shaker rod of Fig. 6 themop head is oscillated on the handle pivot .22. As shown in Fig. 7, uponthe upward oscillation of the mop head the stop member 31 strikes uponthe upper surface of ferrule arm I2, and upon the downward oscillationof the mophead the stop member 38 strikes upon the lower surface of theferrule arm, bringing the mop head at the end of each oscillation to astop with a jolt which forcefully Shakes the mop strands and loosens anddischarges accumulated dust and dirt in the mop body. Obviously, aspreviously described, the rapidity of the reciprocation of the hand gripand rod will determine the force of the jolting stop of oscillations ofthe mop and the eiiciency of the shaking cleaning operation.
